Function points:

1. Web page authorization to obtain WeChat user information

When users access third-party web pages in the WeChat client, public accounts can obtain basic user information through the WeChat web page authorization mechanism, and then implement business logic.

Note: When Scope is snsapi_base, you can only get the user's openid. When it is snsapi_userinfo (an authorization page will pop up), you can get openid, nicknam, sex, province, etc. For details, please refer to the interface document.

Application scenario: Authorization is required for the first time, but no authorization is required later.

The solution is to save the information for snsapi_userinfo for the first time. If it is not the first time, check whether the openid already exists. If it does not exist, jump to the snsapi_userinfo page for authorization. Otherwise, read the information directly.

2. Sharing interface

The interface is relatively simple, just introduce js and follow the official documentation

3. WeChat payment

Activate the WeChat payment function, download the official Demo, lib/WxPay.Config.php and configure various information. It is recommended to use an absolute position for the certificate location to prevent it from being downloaded.
